Description
[0001] The present invention relates to glazing comprising a glazed
element, this glazing being intended to be positioned or fixed on a
structure, notably an automobile bodywork element, by means of at
least one pin. It also relates to a method for manufacturing such
glazing.
[0002] Indeed it is known practice, for positioning or fixing
glazing on a structure, notably automobile bodywork, to use at
least one pin and preferably several pins, or insert(s), that
is/are secured to the glazing beforehand by embedding it/them
partially in a plastic coating, during an operation referred to as
encapsulation or by bonding them in place using a layer of adhesive
material.
[0003] The present invention relates specifically to glazing
comprising a glazed element and at least one pin for positioning or
fixing said glazing on a structural element, notably a vehicle
bodywork element, said pin comprising [0004] on the one hand a base
which is bonded using a layer of adhesive material to a surface of
said glazed element or which has an overmolded part situated in a
profiled-seal portion, and an outer part situated outside of said
profiled-seal portion and [0005] on the other hand a projecting
element which has a guide or fixing head and a foot, said
projecting element comprising means for clipping it to said base
with respect to a vertical central axis A.
[0006] Within the context of the invention it must be understood
that a pin intended to allow the fixing may also, prior to fixing,
be used for positioning.
[0007] In the context of the invention, it must be understood also
that the overmolding may involve a prior step of bonding and that
the bonding may have a prior step of overmolding.
[0008] The pins that allow the glazing to be held and referenced as
it is being mounted on the bodywork may potentially make it
possible to compensate for defects in the curvature of the glazed
element.
[0009] It is difficult to design a correct clipping of the
projecting element to the base because of the environment. It is
important for the glazing to be as close as possible to the
bodywork but the clipping-together of the projecting element and
the base of the pin has of necessity to be achieved between the
surface of the glazed element and the adjacent bodywork; the space
available for clipping is therefore small and needs to be as small
as possible.
[0010] This clipping-together needs to be effective and
reliable.
[0011] It is an object of the present invention to overcome these
disadvantages by proposing glazing with a pin in which the clipping
means guide one another in order to limit the unsuitable forces
which might otherwise carry the risk of causing these clipping
means to break.
[0012] The present invention intends to offer a solution to the
problems of the prior art.
[0013] The present invention thus consists in glazing according to
claim 1. This glazing comprises a glazed element and at least one
pin for positioning or fixing said glazing on a structural element,
notably a vehicle bodywork element, said pin comprising on the one
hand a base which is bonded using a layer of adhesive material to a
surface of said glazed element or which has an overmolded part
situated in a profiled-seal portion, and an outer part situated
outside of said profiled-seal portion and on the other hand a
projecting element which has a guide or fixing head and a foot,
said projecting element comprising means for clipping it to said
base with respect to a vertical central axis A.
[0014] This glazing is notable in that said base comprises [0015] a
baseplate having a lower face facing toward said surface of the
glazed element and an upper face situated away from said surface of
the glazed element, [0016] a body oriented along said axis A from
said upper surface, and [0017] a flange plate situated above said
upper face so that a slot lies between said baseplate and said
flange plate,
[0018] in that said foot comprises at least one flange extending
from said axis A and bent so that its free end is oriented toward
said axis A,
[0019] in that said base also has either a central recess extending
downward without emerging on the lower face of said base, or a
central boss extending upward, and said foot comprises,
respectively, either a central boss extending downward, of
cylindrical or conical shape, or a central recess extending
upward,
[0020] and in that said boss enters said recess and said flange
enters said slot.
[0021] For the mechanical reliability of the clipping it is
important that it is the base that comprises the slot and that it
is the projecting element that comprises the flange (or flanges)
that enters (enter) this slot.
[0022] In this way it is possible to achieve clipping of the
projecting element to the base that is reliable, robust and
compact.
[0023] The base and the projecting element are two distinct
components of the pin.
[0024] The body of the base is preferably cylindrical. The slot is
preferably situated between said baseplate and said flange plate,
all around the body of the base; this slot is thus preferably
annular.
[0025] For preference, the central recess is formed in the base and
the boss if formed on the projecting element because that is the
solution that offers the best guidance between the two components,
while at the same time making it possible to achieve a clipping
that is as compact as possible.
[0026] In this case, for preference, the central recess extends
downward without emerging on the lower face of said base, so as to
maintain the greatest possible surface area for collaboration
between the lower face of said base and the adjacent surface of the
glazed element.
[0027] Said foot, for preference, comprises two flanges both of
which extend from the foot and are each bent so that their free
ends face one another, oriented toward said axis A, said two
flanges entering said slot of said base.
[0028] In this case, said two flanges extend from the foot,
preferably over a radius r of 90.degree., so as to be as wide as
possible and thus provide the most effective possible
retention.
[0029] Said flange at least, or each flange, comprises, for
preference, a spur or a groove and said body respectively comprises
a groove or a spur: the spur, or each spur, is intended to enter
the groove so as to block the position of the flange with respect
to the flange plate, which means to say to block the position of
the projecting element with respect to the base so as to prevent
the projecting element from rotating with respect to the base about
the axis A.
[0030] For preference, each flange comprises a spur or a groove and
said spurs or said grooves are situated facing one another with
respect to the axis A.
[0031] In an alternative form of embodiment, said flange, or each
flange, extends horizontally from said axis A and is bent twice at
right angles so that its free end is oriented toward said axis
A.
[0032] It would be possible for said flange, or each flange, to
extend at an angle that is not a right angle with respect to the
axis A from said axis A.
[0033] For better retention, said flange has, for preference, a
thickness substantially equal to the height of said slot.
[0034] The present invention also relates to a method of
manufacturing glazing according to the invention, whereby in order
to clip together said projecting element and said base, on the one
hand said boss enters said recess and on the other hand said flange
enters said slot by a rotation of said projecting element about the
vertical central axis A.
[0035] Advantageously, by virtue of the invention, the clipping of
the projecting element of the pin onto the base of the pin is
reliable and robust: the risk of the most slender parts of the
projecting element (the flange or flanges) breaking is limited
because these parts are guided by the walls of the slot of the
base.
[0036] A number of embodiments of the present invention will be
described hereinbelow by way of nonlimiting example with reference
to the attached drawing in which:
[0037] FIG. 1 is a face-on view of a first embodiment of a pin
according to the invention,
[0038] FIG. 2 is a view in axial section on BB of FIG. 1,
[0039] FIG. 3 is a side view of the first embodiment of FIG. 1,
[0040] FIG. 4 is a view in section on CC of FIG. 3,
[0041] FIG. 5 is an exploded view of the two components that make
up the pin according to the first embodiment of FIG. 1,
[0042] FIGS. 6 to 9 illustrate the clipping of the projecting
element to the base for the first embodiment of FIG. 1,
[0043] FIG. 10 is a view in axial section of a second embodiment of
the pin according to the invention.
[0044] Within each figure and, in the case of FIGS. 1 to 4 on the
one hand and FIGS. 6 to 9 on the other, the various elements are
drawn to scale and elements in the background are generally not
depicted, in order to make the figures easier to understand.
[0045] FIGS. 1 to 9 depict a pin 4 according to the invention of
which part is intended to be bonded to a glazed element 2 using a
layer (not illustrated) of adhesive material and another part is
then clipped onto this first part. This pin 4 is thus made up of
two distinct components: [0046] on the one hand a base 5 which is
bonded to a surface of said glazed element, and [0047] on the other
hand, a projecting element 6.
[0048] This projecting element 6 has a guide and/or fixing head 61,
intended to collaborate with the bodywork (not illustrated in FIGS.
1 to 9) and a foot 62 which comprises means for clipping it to said
base 5 with respect to a vertical central axis A.
[0049] According to the invention, the base 5 comprises [0050] a
baseplate 50 which has [0051] a lower face 51 oriented toward said
surface of the glazed element 2, in this particular instance toward
an interior face 21 of the glazed element 2, and [0052] an upper
face 52 situated away from the surface 21 of the glazed element,
[0053] a cylindrical body 53, which is oriented along said axis A
from said upper surface 52, and [0054] a rectangular flange plate
55 which is situated above the upper face 52 so that a slot 54 lies
between said baseplate 50 and said flange plate 55.
[0055] According to the invention, the projecting element 6 is such
that the foot 62 comprises at least one flange 64, 64' which
extends from said axis A and is bent so that its free end 65, 65'
is oriented toward said axis A.
[0056] Furthermore, the base 5 has a central recess 56 extending
downward (without opening onto the lower face 51) and said foot 62
comprises a central boss 66 extending downward, and of cylindrical
or conical shape.
[0057] Thus, the central boss 66 enters said central recess 56 and
said flange 64 enters said slot 54.
[0058] It is possible for it to be the foot 62 that has a central
recess, which then extends upward, and for said base 5 to comprise
a central boss, which then extends upward, of cylindrical or
conical shape, so that likewise the central boss enters the central
recess (the notions of "up/down", "upper/lower" and
"vertical/horizontal" as used in this document are with reference
to the vertically oriented axis A as illustrated in FIGS. 1 to 3
and 10).
[0059] The slot 54 is situated between said baseplate 50 and said
flange plate 55 all around the body 53.
[0060] As visible in the figures, the foot comprises two flanges
64, 64' both of which extend from the foot 62 and each of which is
bent twice at right angles so that their free ends 65, 65' face one
another, oriented toward said axis A. These two flanges 64, 64'
enter said slot 54 of the base 5.
[0061] As visible in FIG. 3, the flanges 64, 64' both have a
thickness e substantially equal to the height h of said slot 54,
which means to say the height of the body 53.
[0062] FIG. 4 shows that the two flanges 64, 64' extend from the
foot 62 over a radius r of 90.degree. so as to obtain the greatest
possible area of contact between the flanges and the slot.
[0063] This figure also shows that the flanges 64, 64' each
comprise a spur 67, 67' and the body 53 respectively comprises two
grooves 57, 57' which accommodate these spurs.
[0064] The spurs are situated facing one another with respect to
the axis A, which means to say 180.degree. apart. The spurs 67, 67'
preferably extend over the entire thickness of the flanges 64, 64'
and the grooves 57, 57' preferably extend over the entire height of
said slot 54, which means to say the height of the body 53.
[0065] The flanges 64, 64' extend horizontally from the axis A and
are each bent twice at right angles so that their free ends 65, 65'
are oriented toward said axis A.
[0066] FIGS. 6 to 9 illustrate the clipping of the projecting
element 6 of the preceding figures onto the base 5 of the preceding
figures.
[0067] According to the invention, in order to perform this
clipping, on the one hand the boss 66 needs to enter the recess 56
and on the other hand the flanges 64 need to enter the slot 54 by
rotation of said projecting element 6 about the vertical central
axis A; thus: [0068] in FIG. 6, the projecting element 6 is offered
up near to the base 5 and moved closer via translational movement
in the direction of the axis A (illustrated as inclined in FIGS. 6
to 9 for better legibility); the two flanges 64 are offered up to
face the shortest part of the slot 54 (the two parts of the slot
that are of least depth); [0069] in FIG. 7, the two flanges 64 are
introduced into the two parts of least depth of the groove 54;
[0070] in FIG. 8, the projecting element 6 has been rotated by
one-eighth of a turn with respect to the previous figure, about the
axis A; the two flanges 64 are half engaged in the two parts of
greatest depth of the slot 54; [0071] in FIG. 9, the projecting
element 6 has been rotated a further eighth of a turn with respect
to the previous figure about the axis A and is now clipped onto the
base 5: the two flanges 64 are completely housed in the two deepest
parts of the slot 54; furthermore, in order to block the position
of the projecting element 6 with respect to the base 5, the two
spurs (not visible in this figure) have entered the corresponding
two grooves.
[0072] FIG. 10 illustrates a second embodiment of the invention, in
which: [0073] the base 5 has an overmolded part which is situated
in a profiled-seal portion 3: the baseplate 50 except for the upper
face 52 thereof and [0074] an outer part of the base 5 is situated
outside said profiled-seal portion 3: the upper face 52, the body
53, the flange plate 55 and the slot 54.
[0075] FIG. 10 also illustrates an example of the collaboration
between the projecting element 6 and the bodywork 8.
[0076] In order partially to encapsulate the pin 4 on the glazed
element 2 as depicted in FIG. 10, the procedure described
hereinbelow may be followed in succession: [0077] the glazed
element 2 is placed in a lower part of a mold, [0078] the pin (or
the various pins) 4 is (or are) (each) placed in a cavity provided
in an upper part of the mold, [0079] the mold is closed; during
this operation a sealing element, such as a seal for example, is
pressed firmly against the upper face 52 of the baseplate 50 to
ensure a good seal and prevent injection material from encroaching
on this upper face, [0080] the plastic is injected into the molding
cavity in order to form the profiled-seal portion 3.
